We put our 3 week broilers out in the chicken tractor today. It is going to be 50 overnight. Will they be okay? The tractor has a portion that has a roof and sides covered. It isn’t supposed to rain.They only had heat in the brooder for the first week and they have been in our garage since we got them. I went out and checked on them. They are sleeping in a pile and are not chirping excessively. They are mostly feathered and were outside in 60 degree weather with no issues. They were up scratching, eating, drinking, and trying to dust bathe in the grass.
